Introduction on DC DC Converters

A DC-DC converter is an electronic device that converts direct current (DC) voltage from one level to another. It is also known as a DC converter, DC step down regulator, DC-DC regulator, or DC to DC converter. The DC DC converter basically takes a voltage from one level and regulates its output to a different level, usually in the same direction, but it may also be used to convert from a positive voltage to a negative voltage. The DC DC converter is used for power conversion in a variety of electronic devices, such as computer hardware, automotive applications, telecommunications, medical equipment, and instrumentation. It is also used to step down AC voltage into DC voltage for powering solar systems, aircraft, and more. The DC-DC converter enables permanent control of voltage, current, and power at the output.
